You will love it if: 1: You felt 2001 could have been even slower paced and still be awesome 2: You love really thinky sci-fi even if it doesn't involve people shooting aliens 3: You are crazy in love with 80's hair styles and weird synth music (this movie takes place in 1983, and takes that responsibility VERY seriously) 4: You loved Agent Smith's delivery of lines in The Matrix, and would have liked it if he talked even more slowly and threateningly 5: You think the only good sci-fi is 70's Russian sci-fi
You will hate this movie if: 1: You enjoy having more than one person deliver lines over the course of two hours (basically one speaking part in this movie, though the actor does a good job) 2: You don't like when movies are very, very pretentious 3: You like your movies to generally make an effort to make sense (at one point I swear the main guy gets a phone call from Speak-n-Spell) 4: You don't like when movies spend a considerable amount of their running time trying to injure the viewer's senses 5: You like a really good ending (if you look over the reviews, whether people loved or hated this movie everyone agrees the ending was weak)
All things considered, I really liked this movie, and so did the people I saw it with. But that's a bunch of film geeks. If you're a weird film geek too, I recommend it.
